So I was wondering what the general consensus was on doing costumes from kind of obscure books? I know that people cosplay from blatantly popular books like Harry Potter and Twilight all the time, but some of my all-time favorite books are definitely less well known and I really want to cosplay some of their characters!

I plan on doing:

Mary Katherine Blackwood from We Have Always Lived in the Castle
Weetzie Bat from Weetzie Bat
Alice from The Magicians

Have you ever cosplayed from a less-than-popular book? What was the response? Where did you wear the costume to, if you wore it anywhere at all?
